Native Android apps, without the installation
With
Google Play Instant, people can use an app or game
without installing it first. Increase engagement with your Android app
or gain more installs by surfacing your instant app across the Play
Store and Google Play Games app.
Android’s new app publishing format, the Android App Bundle, makes it easier than ever to offer a Google Play Instant experience. Starting from the Android Studio 3.3 beta release, you can build and publish one app bundle artifact to Google Play containing both instant and feature modules. Build instant games easily with Cocos and Unity plug-ins.
Google Play Instant is open to all app and game developers.
